Tony,
You have a BRNO, is it mititary? The 7.62 is throwing me off, as that was usually a commercial chambering for BRNO.
BRNO are very good actions, some depending on the model are in the top two or three mauser type actions ever made, very desireable and really make a fine rifle with a little work. If its already a .308 does it have ZKK 600 or 601 marked on it anywhere? It also could be a converted VZ-24. If your real lucky it could be a G33/40 but you would see a Nazi eagle on it just at the stock line.
No I am not a real big fan of your barrel choice and now you tell me your working with a BRNO action I am less impressed. Simply they are to nice of action to put that quality barrel on.
First we need to figure out exactly what BRNO you have though, they made large ring and small ring actions and if its a small ring those barrels won't fit anyway, they are too big.
I have several barrels I like, some are a lot more expensive than the one you were looking at, so I won't suggest them. In a good barrel at a reasonable price Douglas makes a good barrel out the door you should have it chambered, crowned, threaded and polished for just over $200. Next step up to a real quality barrel is Lothar Walther and they make pre threaded barrells also, but they are in the $200 price range. They are a real quality barrel though. Shilen makes good barrels also I know they do pre threaded match barrels not sure on the cheaper lines.
Let me caution you about the pre threaded barrels, Adams and Bennett say you can finish them with hand tools. Maybe in theory possible, but very difficult and very easy to hose up your barrel. The pre threaded barrels are short chambered and need a finish reamer run in them, best way to do that is a lathe, unless you have one and access to the reamer I would have this done proffesionally. Just renting the reamer is going to cost you $35-40 and a gunsmith will do it for not a whole lot more than that.
A quote from their site:
As we have mentioned before, a qualified gunsmith should install any of our short-chambered barrels or barrel blanks, finish-ream the chamber, properly headspace and test-fire (or at least be part of the process.
I admit I am a BRNO fan, their not near as common as the used to be and really top quality actions, I have one in my custom rifle que right now. I will true the action, lap the lugs, and polish mine, with a quality barrel and I expect .65-.75 MOA groups from mine, with a your .308 if your careful you might get sub .5 MOA out of it. Since it is a 308 I would put a short stiff tube on it, a #2 or #3 contour with a 20-22" barrel is ideal. One last tricky question? What bullet weights are you planning on shooting, you really should match that up to your barrel twist, in my 308 I shoot 168 gr bullets and my twist is 11 to 1 ( actaully 11 and a small decible ) this is a perfect match of twist to bullet type. If your planning on 180-200 gr bullets the 10-1 is good, and 150 gr and lighter work best with a 12-1.
One last caution old mausers are money sucks, no getting around it, but bad choices in barrels make them really hard to move. When I am buying I will hold to the price of the action value with a Adams and Bennett barrel, if I really liked the action I would add $25.00 to the deal not any more. I know I am a picky old crusty type but there are a lot of us types around.
Here is the Douglas site:

Walther:

I have several custom rifles and own one of each of the above ( and several other high dollar ones also ) both are excellent quality and not going to break your bank roll as these are good value barrels.
If your really trying to save some dollars take a look on Auction Arms or Gunbroker. You can find deals on barrels in the $100 range that need threading and chambering, another good place to look is the benchrest thread want ads. The benchrest guys buy top quality barrels and as soon as they figure there shot out sell them ( translated when they aren't getting .2-.25 MOA groups ) many times you can pick up one of these slightly used barrels cheap, downside is they are usually a heavier contour.
Look for some more markings on your BRNO action, lets figure that out first, letting me know if it is military or commercial will narrow the field a lot. One last question is this a CZ? Does it have a removeable magazine? CZ and BRNO is very confusing unless I go into a long story, they were different, then the same, and now different again. Years of production are the identifiers when figuring it out. Good news is either way these are both good rifles.
